BCL2 and gastric carcinoma: BBR modulates the activity of the Bcl-2 family members; increased expression of pro-apoptotic protein Bax (Bcl-2-associated X protein) together with decrease of Bcl-2/Bcl-xL after BBR treatment was observed not only in human prostate epithelial (PWR-1E) or carcinoma cells (DU145, PC-3 and LNCaP), but also in promyelocytic leukemia, gastric carcinoma and lung cancer cells, inducing cell death (Table 1).
